We used to have a large company servicing our heat pump. During a regular maintenance, we were told we need a new motor although we did not have any problem. So we replaced the motor. But we've never got enough air coming out of the vent after that. After they failed to fix it several times, we fired that contractor.
Someone recommended Sherman to us and he replaced a controller on his first trip and the problem solved. We now get enough heat and AC when ever we need. Highly recommended !!
Pros: Excellent HAC knowledge and experience
